I found it...
I've been looking for a cap like this for a long time. It's quite comfortable; design fits well on the head; headband is wide and comfortable; adjustible cord from the back give customized fit and can be adjust to windy conditions; material is light-weight; and two vents on each side for air-flow and circulation. Cap bill is foldable so you can pack it tight including your back pocket. I also like the style; simple and functional. A little more than what I expected to pay but worth the extra and the wait.
